Visiting his Late Night predecessor David Letterman for the first time since 1999, talk show host Conan O'Brien took the opportunity to discuss the infamous Tonight Show debacle with a man who knows a thing or two about Tonight Show debacles.

"I was delighted by everything that happened — except you losing your job," Letterman said. "The only consolation I took during that period was that you were happy," Conan retorted.

Letterman did have some nice things to say about his arch-rival, noting that he thought Leno was "always...the funniest guy," but also "a bit of a brat."

On a more positive note, Conan remarked that he was "thrilled" about how the ordeal ended. "It worked out," he said. "I'm a lucky person."
